I was asked by an unhappy movie producer why a writer could turn in a fine script, but the next one by the same writer would be bad. Here’s my answer:

We writers ask ourselves the same thing. Why is one piece of writing successful, and the next one isn’t? We worked on it the same way, just as hard, with the same excitement and love, and no one liked it. Why?

Well, among other reasons, unless we’re rewriting the same thing over and over, or following a formula as if creative works were McDonald’s hamburgers, every story is an experiment. Sometimes experiments fail.

"You write a hit the same way you write a flop," said Alan Jay Lerner of the writing team Lerner and Loewe. Lerner won three Oscars, among many other awards, and everyone in the world has heard his hits, which include My Fair Lady, Camelot, and Gigi. He also wrote 1600 Pennsylvania Avenue with none other than Leonard Bernstein as a collaborator, and it’s perhaps the worst flop in the history of Broadway.

What went wrong? Nothing. The creative process went as normal. There are no guarantees. Martin Amis called bestsellers a “ridiculous accident”.

This is why writers drink. We can, perhaps, accept the inevitability of random failure, but those around us don’t always understand.
